This is an iOS app that allows for the opening and analysis of DNA sequencing files - ab1. It includes handy tools such as "Reverse Complement", "Jump to", "Copy and Paste sequences", fast and end scrolling, "Chromatogram adjustments", and "Searching for segments" functions.

When used in combination with other zip apps, and also web-tools like Blast, this app allows you to analyze, and also determine the quality of your sequencing files.

This app works with cloud storage access like Dropbox to your sequencing files.

This is now compatible with the new update for iOS 7.1.
